摘要
访问授权是分布式系统中关键的组成部分之一,但一般没有作为独立节点实现,甚至被忽略。本文提出并实现了一种基于XACML构建策略决策点的安全模型,给出了模型三种应用基本模式,使模型适应各种环境需求,实现安全的细粒度访问控制。
Access control is a key component of a distributed system, its implementation always depends on other modules, if it is not ignored. This paper describes the research and implementation of a new Policy Decision Point system based on XACML, and presents three kinds of configuration models of PEP and PDP, so this system could be applied in many kinds of distributed systems.
